How sure are you about the facts listed? Some seem a bit doubtful to me.

27 and 47 Msl Regts existed roughly 1959 - 1965, they were equipped with the Corporal SSM system, one regt was assigned to 1 (BR) Corps the other to 1 (GE) Corps. After 1965 they became normal field or medium regts and their R Signals component was probably no more tha a rear link det.

Hy AD Regts, 36 and 37, were equipped with Thunderbird. My memory is that they had a R Signals sqn to provide data links between and within btys using RR eqpt.

I think 1 Arty Bde HQ and Sig Sqn was based in Hildesheim in the 1960s, before the first of the new Hy Regts (M107 175mm) moved in, in about 1966.

I'm pretty confident of my sources - i was at 604 in the early 80's and started to research the whys and wherefores of the unit.

There isnt much recorded in Royal Signals Corps history - a foot note really so I began to trace the antecedents. It would appear that most of the Royal Siganls GW and NC requirements in the late 60's were born out of a much older tradition of Royal Artillery Signals Troops and Royal Signals AA support troop/squadrons.

I have a number of credible sources UK/USA/GE/NL/BE/Russian

I'd be grateful if you PM, i'd like to exchange emails and swap notes if your interested.
